TABULATING DEVICE FOR VTYPE-WRITING NIACHIN'ES.

SPECIFICATION forming part of Letters Patent No. 767,839, dated. August 16, 1904.

Application filed October 21, 1903. Serial No. 177,877. (No model.)

To (all whom, it may concern.-

Beit known that I, JEROME B. SEcoR, a citizen or' the United States, residing at Derby, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Tabulating Devices for Type-VVriting Machines, of which the following is a specification.

This invention relates to improvements in tabulating devices for type-writing machines, and has for its object to provide a tabulating stop device which will serve as a column-stop and which is adapted to be connected with and automatically actuate the release device or not, as desired.

The invention comprises an adjustable stop device mounted on the frame of the machine and adapted to be used in connection with and moved into the path of a series or' dogs mounted on the carriage of the typewritersuch, for instance, as shown in my application for Letters Patent filed July 9, 1903, and serially numbered 164,819. In such application I have shown a range of dogs mounted at fixed distances apart from end. to end of the carriage -by pivots or otherwise, so as to adapt them to be separately slid transversely to the carriage into or out of cooperating position with relation to the stop device on the trame, such carriage-dogs being mounted at suitable distances asunder on the carriage to provide for printing' as many columns as desirable from side to side of the paper carried oy the platen. In the invention described in the said application and in the present invention such carriage-dogs and also the stop device on the carriage-frame rest normally in retracted position, leaving the carriage free for ordinary type-writing work, the type-writer acting satisfactorily Without regard to the position of the dogs on the carriage that is, whether the same are set or notkwhile the tabulator will act only with reference to those dogs on the carriage which have been set. When column work is to be done, the selected carriage-dogs are set into operative position to locate the several columns, and the stop device on the frame ismoved into operative relation to the carriage-dog to determine the decimal value or' the first igure to be printed in the column. In the invention described in the said application the operation of the stop device on the machine-frame was not dependent upon or connected with the operation of the releaselever. In the present application I have shown an adjustable stop device which may be and preferably is connected with the release-lever of the machine or which may be employed without being connected to said release-lever.

The present linvention relates particularly to a stop device mounted on the machineframe, which need not be restricted to use with any particular form of carriage-stop dogs and which is simple of construction, highly eiiicient in use, and adapted to be operated by a single key or lever.

Further objectsoi' my invention are to pro- .vide .a suitable means whereby the releaselever of the type-writing machine may be actuated automatically upon the operation of the said stop device.

In the accompanying drawings I have shown a practical application of my improved tabulating mechanism to a type-writing machine, showing only those parts ot' the machine which are necessary to illustrate the invention.

In the drawings like reference-numerals refer to like parts.

^ Figure 1 represents a front view of a portion oi' a type-writing machine provided with my improved tabulating mechanism. Fig. 2 is a longitudinal sectional view ofthe same. Eig. 3 is a plan View of the same. Fig. 4 is a bottom view of a portion of the front bar of the carriage, showing a series of marginal or column-stop dogs mounted thereon. Fig. 5 is an edge view of the same. Fig. 6 is a detail sectional view showing a portion of the machine-frame and the hey-mounting oil my improved tabulating mechanism. Fig. 7 is a detail view showing modifications in the tabulator key or lever and its mounting.

Referring now in detail to the drawings, l represents the machine-frame, having mounted thereon the carriage track-bar 2, in which travel balls 3, which support the carriage 4.

is the 'front bar of the carriage 4, having pivotally mounted thereon a series o't' marginal or column-stop dogs G, pivoted at7 and movable transvcrselyto the direction o'tf travel of the carriage 4. The dogs 6 rest normally in retracted position and when operated are adapted to be thrown into the path of the stop device hereinafter described and mounted on the carriage-frame. The movement of each of the dogs 6 is limited by the pins Sengaging the notches 9 in the said dogs.

rIhus far the mechanism described has been disclosed in the application hereinbe'lore re- Yferred to and does not form a part of my present invention. I will now proceed to describe my improved stop device mounted on l the frame of the machine to be used in coperation with the Jforegoing carriage-dogs.

Bolted at the front of the frame 1 of the machine is a bracket 10, through one end of which passes the joint-screw 11, on which is pivotally mounted a segmental gear 12, having a squared shoulder 18, adapted to abut the bracket 10 and space the gear 12 therefrom.

14 is a lever provided with a U-shaped lower end adapted to lit snugly on the shoulder 13 and being secured on said shoulder by a pin 15. than the space between the gear 12 and the bracket 10, allowing' for a slight vibratory movement, and is curved 'forward upwardly and forms at its upper end a key 1G, having a tooth 17 and acup-shaped gripping depression 18.

Positioned above the joint-screw 11 on the frame is a scale 19, having suitable indicia thereon, and teeth 20, arranged radially from the joint-screw 11. The teeth 2O are cut at right angles to the face ot' scale 19 on the right and are beveled from the bottom upwardly to the left in the form ot' ordinary ratchet-teeth. Pivotally mounted at 21 on bracket 10 is a segmental gear 22, engaging the teeth on the gear 12. y

23 is a bracket supporting a ,joint-screw 24, on which is pivotally mounted an extension 25 of the segmental gear 22, which extends at right angles to the said gear 22.

26 is a link rigidly secured at its lower end to the link v25 and pivotally connected at its upper end to a pawl 27, slidably mounted in a slot in the top of the `frame 1. Pawl 27 is provided with a lug 28, adapted to prevent the removal of the pawl 27 from its slot, but allowing a limited pivotal movement of the said pawl. As shown in the drawings, the pawl 27 is in suitable position to be elevated into the path of any one of the carriage-dogs 6 which may be set to engage the same;

In order to automatically elevate the pawl 27, I have provided a push-bar 29, located immediately beneath the teeth 2O in position to be pressed in upon engagement o1 the actuating-key with the teeth 20.

Lever 14 is of slightly lesser `thickness j 25 and link 26 to the pawl 27.

is made in length about equal to the scale 19 and series of teeth 20, as shown in Figs. 1 andv 3, so as to adapt it to be acted on by the lever 14 in any angular position to which this may be deflected to the right or left. The pushbar 29 is provided with extension 30, extending rearwardly through the machine, having adjustabl y mounted thereon an elevating-finger 31.

Pivotally mounted above the elevating-1inger 31 in position to be raised thereby is a lrame 32, carrying' a plate 33, resting immediately under and in engagement with the pawl 27. a rigid extension of the finger 31, and the frame 32 may be thus done away with.

In the operation of my improved tabulating mechanism the operator grasping the key 14 at the cup-shaped gripping depression 18 and moving' the same Ato the lett forces the pawl 27 to a desired point on the scale 19, indicating the point in the travel or' the carriage where it is desired to have the stop 27 intercept-ing a selected carriage-dog to determine the value of the irst tigurein the column of' the iigures to be recorded. It will be readily seen that the movement of the lever 14 communicates motion to the gear 12, through gear 12 to the gear 22, and thence from the extension The scale 19 is preferably provided with three groups of .short straight lines separated by decimal points to indicate hundreds, thousands, and millions, or any suitable indicia may be employed to indicate the same. The scale 19 reads in the same direction as the travel of the carriage, and I am enabled to have the same read thus because of the segmental gear which reverses the movement of the parts. The use of the gearing between the key-lever 14 and the movable stop enables'me to make the index-notches on the scale or' greater distance apart than the spacing of the lettering on the printed sheet carried by the platen because or' the difference of diameter ot the gears 22 and 12, thereby making it much easier to find the desired point or notch on the scale 19. It it obvious, however, that the key-lever 14 may be mounted on the same axis with the extension 25, in which event, of course, the scale would have to read in the opposite direction. It will be readily seen that through the provision of the scale 19 and the graduated carriage-dogs 6, having on the latter suitable indicia, the operator can bring the carriage after having set the desired dog 6 to any position in its travel through the forcing into engagement with the desired tooth 2O of the key 16 and releasing the carriage from its escapement dog or dogs, which may be done through use. of the usual release-bars or through the automatic release mechanism hereinafter described. In forcing the key 16 into engagement with the particular tooth 20 the push-bar 29 is forced in- The push-bar 29 l, wardly, pushing the lingerl beneath the shoe Itis obvious that plate 33 may constitute loo freres@ 32 and through the lip 33, forcing the pawl upwardly into the path of the particular dog 6 which has been set.

In the drawings I have shown as a part of my invention an automatic release device, whereby upon manipulation of the key 16 and forcing the said key into engagement with the particular tooth 20 the carriage may be released to travel until stopped by the engagement of the particular dog 6 on the said pawl 27. Such an arrangement consists in an elongation to the extension 30, pivotally secured at its rear end to a link 34, extending upwardly from the bar 30 and rigidly connected to a' pin in 35, journaled ina U-frame 36. 37 is a shoe positioned above the general releasebar 38, having rearward extension suitably bent and rigidly mounted on the pin 35. When the bar 30 is forced inwardly, the link 34 is forced rearwardly, turning the pin 35 and through the same depressing theshoe 37,

forcing down the general release-bar 33, releasing' the carriage to travel until stopped by the clogging means. Anyv suitable means may be used for throwing out the escapement when the general release-bar is actuated. In the present instance I have shown merely to illustrate the principle of operation a part of an escapement mechanism of my own, which,

however, does not form an essential part of my present invention. Therein I employ the frame 39, fulcrumed to the frame of the machine and having a lip 40 immediately beneath the general release-bar 38. Extending rearwardly from the frame 39 is the arm 41, bent rearwardly to engage an escapement-dog 42 and to force the same out of engagement with an escapement-wheel 43 when the general release-bar 38 is depressed. v

In Fig. 7 I have shown slight modifications in the mounting of the lever 14 and in the structure -of the same and of the key 16. Therein I have made thelever 14 with an eX- tension 44, forming the segmental gear 12, adapted to the gear 22. I have also shown the lever 14, controlled by a spring 45, mounted on the joint-screw 11, adapted to hold the lever 14 normally at the right end of the scale 19. In order to provide for the vibration of .the key 16, I have made the same separate from the lever 14 and pivoted thereto at 46.
